Ok I'm looking at the FSM for yota pickup 4X4 1994 V6 with starndard power steering setup. It says there is a bleed valve on the steering gear box you should connect clear hose to and get air our of system.

Well I've looked everywhere on my steering gear box and I only see the hex nut in the center with teh flat head adjustment screw.

Can anyone tell me where the bleed valve is on the steering box ???

I'm getting a new PS reservoir today (mine is leaking) and I want to bleed the system correctly. Chilton manual also describes this BLEED VALVE.

 

Personally I haven't ever used a bleed valve on power steering just poor in fluid and with the front end off the ground and the car running turn steering lock to lock several times watching your fluid level.
